The red haired singer, 25, was once a judge on a fashion show but admitted that she didn’t enjoy the experience and wouldn’t do it again.

She toldCompanymagazine: ‘I did a bit of judging for Britain’s Next Top Model and I hated it. I could see the girls getting upset and I remembered what it was like when I was in their position.

‘You can’t be b****y or flippant – I find it difficult to criticise, I mean, who am I to judge? No, that’s Cheryl’s job.’

Roberts also touched on her relationship with her Girls Aloud bandmates, claiming that although they don’t plan on recording together in the foreseeable future, they’re still as close as family.

‘Cheryl and Kimberley (Walsh) are like my sisters,’ she said. ‘But we don’t get to see Sarah as much as we’d like because she lives in Buckinghamshire.’

She added: ‘As soon as we’re together, it’s like we’ve never been apart.’

The Lincolnshire-born star didn’t comment on her relationship with Nadine Coyle, often seen as the outcast of the group, but said her and the other girls liked to relax and watch soap operas when they’re together.

She said: ‘We’ll have a night in dressed in trackies or PJs, with rubbish hair and no make-up.

‘We stock up on oven chips, chicken nuggets, olives and sweets, and put on EastEnders, which we then just talk over all night!’
